srsUE is not connecting when selecting 5MHZ bandwidth #1466

Description

@Waseem0808

I am unable to connect a SRSUE to gNB when choosing a 5MHZ bandwidth.
I am getting this error:
2026-01-31T20:46:07.671863 [PHY0-NR] [E] [ 1441] PDCCH: rnti 65535 isSrb=1
2026-01-31T20:46:07.671869 [PHY_LIB] [I] [ 0] PDCCH DMRS Rx: Measure L=2; ncce=0; RSRP=-1.6 dBfs; EPRE=+15.2 dBfs; Corr=0.021 2026-01-31T20:46:07.671871 [PHY_LIB] [I] [ 0] Discarded PDCCH candidate L=2;ncce=0; Correlation is too low (0.0<0.5); EPRE=+15.17; RSRP=-1.65;

Here is my tested configuration.

gnbConfig1.txt
gnbConfig2.txt
ue.txt

I tried various other configurations but no luck.
Please let me know whether a 5MHZ is supported by srsUE? or If some 5MHZ specific config is missing.

I would also like to add that a 10MHZ config is working.
